# `prefect.deployments.runner`



Objects for creating and configuring deployments for flows using `serve` functionality.

Example:
    ```python
    import time
    from prefect import flow, serve


    @flow
    def slow_flow(sleep: int = 60):
        "Sleepy flow - sleeps the provided amount of time (in seconds)."
        time.sleep(sleep)


    @flow
    def fast_flow():
        "Fastest flow this side of the Mississippi."
        return


    if __name__ == "__main__":
        # to_deployment creates RunnerDeployment instances
        slow_deploy = slow_flow.to_deployment(name="sleeper", interval=45)
        fast_deploy = fast_flow.to_deployment(name="fast")

        serve(slow_deploy, fast_deploy)
    ```



## Functions

### `deploy` <sup><a href="https://github.com/PrefectHQ/prefect/blob/main/src/prefect/deployments/runner.py#L1139" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>

```python
deploy(*deployments: RunnerDeployment) -> List[UUID]
```


Deploy the provided list of deployments to dynamic infrastructure via a
work pool.

By default, calling this function will build a Docker image for the deployments, push it to a
registry, and create each deployment via the Prefect API that will run the corresponding
flow on the given schedule.

If you want to use an existing image, you can pass `build=False` to skip building and pushing
an image.

**Args:**
- `*deployments`: A list of deployments to deploy.
- `work_pool_name`: The name of the work pool to use for these deployments. Defaults to
the value of `PREFECT_DEFAULT_WORK_POOL_NAME`.
- `image`: The name of the Docker image to build, including the registry and
repository. Pass a DockerImage instance to customize the Dockerfile used
and build arguments.
- `build`: Whether or not to build a new image for the flow. If False, the provided
image will be used as-is and pulled at runtime.
- `push`: Whether or not to skip pushing the built image to a registry.
- `print_next_steps_message`: Whether or not to print a message with next steps
after deploying the deployments.

**Returns:**
- A list of deployment IDs for the created/updated deployments.

**Examples:**

Deploy a group of flows to a work pool:

```python
from prefect import deploy, flow

@flow(log_prints=True)
def local_flow():
    print("I'm a locally defined flow!")

if __name__ == "__main__":
    deploy(
        local_flow.to_deployment(name="example-deploy-local-flow"),
        flow.from_source(
            source="https://github.com/org/repo.git",
            entrypoint="flows.py:my_flow",
        ).to_deployment(
            name="example-deploy-remote-flow",
        ),
        work_pool_name="my-work-pool",
        image="my-registry/my-image:dev",
    )
```
